Abstract

The invention relates to the field of wastewater treatment, and particularly relates to a copper-containing electroplating wastewater treatment device and method. The device and the method are characterized in that the device comprises a copper-containing wastewater regulating tank, a copper coagulation reaction sedimentation tank, a copper-containing sludge tank, a copper-containing sludge concentration tank and a chamber type filter press, wherein the copper-containing wastewater regulating tank, the copper coagulation reaction sedimentation tank, the copper-containing sludge tank, the copper-containing sludge concentration tank and the chamber type filter press are sequentially connected in series through pipe fitting valves; clear water outlets of the copper-containing sludge concentration tank and the chamber type filter press are connected with an inlet of the copper-containing wastewater regulating tank; sludge of the chamber type filter press enters the sludge treatment unit; and copper-containing and comprehensive wastewater in the copper coagulation reaction sedimentation tank is treated and enters a mixed wastewater regulating tank. The invention aims to provide the copper-containing electroplating wastewater treatment device and method, so that the system can be used for accurately treating various electroplating wastewater.

Description

[0001] This case is a divisional application with the title of the invention "a system for the separation and treatment of electroplating wastewater in centralized control areas", the application number "2019114081810", and the application date "2019-12-31". technical field [0002] The invention relates to the field of wastewater treatment, in particular to a treatment device and method for copper-containing electroplating wastewater. Background technique [0003] The wastewater output of the electroplating industry is less than that of papermaking, printing and dyeing, and chemical industries. However, due to the wide distribution of electroplating factories, there are many types of harmful substances contained in electroplating wastewater. Therefore, the treatment of electroplating wastewater is very important. Electroplating wastewater mainly contains chromium, zinc, copper, lead, nickel and other heavy metal ions, as well as carcinogenic cyanide. If these substances are...
